How to make the Canvas App id constant across environments?

Posted on by MadhanSA 115

Hi,

I have an embedded canvas app in my development enviroment. When I export this app as a package and import it in my test environment, the App ID is getting changed. Because of this, I need to manually change the App ID in the form where I am using it. Is there any way to export the app with the same ID?

Thanks,

Madhan

    Hi Madhan,

    In practice, you shouldn't need to change the App Id in order for the embedded canvas app to work.

    Are you facing any specific error when you don't change it?

    Additionally, the user you are using when opening the form is a system admin? If not, can you check if the user has Organization level read permission to an entity called "Canvas App"?  

    Let me know the result of the testing and any feedback from this.

    Thank you.

    In my experience, when extending a modeldriven app with a canvas app, it is to provide some custom functionality. Therefore we start in our DEV organization. Creating the canvas app also in the DEV organization, causes the embedded canvas app to refer to the canvas appid of the DEV organization.

    Deploying both the modeldriven as the canvas app to another organization will generate new appids. When you test the embedded canvasapp, the initial canvas app is shown (from the dev environment) and seems fine.

    Since the canvas app is interacting back to the modeldriven app trough the "ModelDrivenFormIntegration", it updates my DEV organization.

    This is not the intended behaviour.

    I wrote a plugin that copies the correct appid(from a env variable) to a custom appid field on crate of my record. The canvasapp control has the appid bound to that appid field.

    It's not nice, it's a workaround, but it works.

    Hi All,
     
    I stumbled into the same thing and ended up solving it like this:
     
    Added a simple table where I store the APP id's per environment:
     
     
    And created a eventhandler to set the correct AppId for the current environment:
     
        [FormDataSourceEventHandler(formDataSourceStr(LedgerJournalTransVendInvoice, LedgerJournalTrans), FormDataSourceEventType::Activated)]
    public static void LedgerJournalTrans_OnActivated(FormDataSource sender, FormDataSourceEventArgs e)
    {
        FormRun formRun = sender.formRun();
        PowerAppsHost powerAppsHost = formRun.design(0).controlName("PowerAppsHost"); //Get the PowerApp control
        PowerAppsIds powerAppsIds; //Table holding the PowerAppID

        select firstonly powerAppsIds
            where powerAppsIds.Environment == XXX_General::checkEnvironment() 
            && powerAppsIds.AppName == @"Attachment";
       
        powerAppsHost.AppId(powerAppsIds.AppId);
    }
     
    That XXX_General::checkEnvironment():
     
        static XXX_Environments checkEnvironment()
    {
        var env = Microsoft.Dynamics.ApplicationPlatform.Environment.EnvironmentFactory::GetApplicationEnvironment();
        XXX_Environments ret; //Enum holding Prod, UAT2, UAT1 and Other

        switch(env.Infrastructure.FullyQualifiedDomainName)
        {
            case "prodURL.operations.dynamics.com":
                ret = XXX_Environments::Production;
                break;
            case "UATURL.sandbox.operations.dynamics.com":
                ret = XXX_Environments::UAT1;
                break;
            case "PreProdURL.sandbox.operations.dynamics.com":
                ret = XXX_Environments::UAT2;
                break;
            default:
                ret = XXX_Environments::Other;
                break;
        }

        return ret;
    }
    Maybe this helps someone.
     
    Cheers,
    Gerard
